摘　　要：考察了结晶器电磁制动技术在板坯连铸过程中的应用效果,比较了电磁制动对结晶器内钢液火焰状态和温度分布的影响,结果表明:合理的制动电流可使结晶器内钢液液面波动降低、火焰均匀分布,燃烧状态达到最佳,过大和过小都不利于火焰燃烧状态和传热的均匀性;施加电磁制动可显著提高结晶器内钢液温度分布的均匀性,平均温差由10℃降低到4℃;合理使用电磁制动有利于提高保护渣渣耗且使保护渣熔化更均匀,本研究条件下的吨钢渣耗提高了0.021 kg;铸坯质量检验表明,使用电磁制动可降低铸坯中氧化夹杂物含量,对于试验条件下的低碳钢全氧质量分数降低了49%。The application effects for FC-Mold （Flow Control Mold） technology are researched in slab casting process, and the flame status and temperatures distribution in mold are emphasis researched. The results show that ： the flame can uniform distribution in the surface of liquid steel by using appropriate current, and irrational current will not favorite to heat transfer and flame status. The temperature distribution is uniform by applying FC-Mold technology, and the average temperature difference can be decreased from 10 ~C to 4 ~C. The mold slag consumption can be increased by using appropriate FC Mold technology. And the mold slag consumption is increased 0. 021 kg/t in experimental conditions. The oxide inclusion content in slab can be decreased 50% by using appropriate FC-Mold technology.
